It's more about the irrational hatred of everything Obama.
Actually no. Obama has never made any bones whatsoever about his hatred of "colonialism" and what it entails. While he has never expressed outward "hatred" for either Israel or England - his actions speak louder than words. You grow up as a communist (with a Father that was supposedly a "victim" of colonialism) and then are mentored by a devout communist - what the hell else could one believe?
Again, I am a proud American. I am also a supporter of Israel. Always have been and always will be. If it rankles a few feathers, so be it. I would take Netanyahu any day of the week and twice on Sunday before Obama.
